RAILWAY VEHICLE UNDERFRAME Filed Oct. 17, 1931 3 Sheets-Sheet 3 In V6)?far Patented July 5, 1932 UNITED, STATES PATENT OFFICE ADELBERT G.WINTEMBERG, OF DREXEL HILL, PENNSYLVANIA, ASSIGNOR TO GENERAL STEELCASTINGS CORPORATION, OF GRANITE CITY, ILLINOIS, A CORPORATION OFDELAWARE RAILWAY VEHICLE UNDEBFRAME Application filed October 17, 1931.

The invention relates to railway rolling stock and consists in animproved construction of underframing for railway vehicles intendedprimarily to carry water and fuel and the invention is particularlyadapted for use in locomotive tender construction.

One object of the invention is to provide a simple and inexpensiveunderframe casting which in itself may form the bottom of a locomotivetender structure and upon which the sides and ends of the superstructuremay be mounted thereby lightening the weight of the-tender byeliminating a separate tank bottom.

Another object of the invention is to embody novel features in spacedcenter sill construction for supporting the vertical longitudinalmembers of a coal hopper superstructure mounted on and near one end ofthe underframe.

Another object of the invention is to provide novel features inconstruction of the underframe and rear end draft gear pocket integraltherewith for transmitting the pulling and bufiing forces set up in thedraft gear pocket to the center sill members of the underframe.

The invention consists in all the novel features hereinafter disclosedand illustrated in the accompanying drawings in which A Figure 1 is atop view of a locomotive tender underframe embodying the invention.-

Figure 2 is a longitudinal vertical section of the underframe takenalong the line 22 of Figure 1.

Figure 3 is a side view of the underframe.

Figure 4 is a rear end view of the underframe.

Figure 5 is a front end view of the underframe..

Figures 6 to 11 inclusive are detail transverse vertical sections takenalongthe lines 66, 77, 88, 9-9,- 1010, and 1111 respectively of Figure1.

Figure 12 is a fragmentary detail horizontal section taken along theline 1212 of Figure 3. v

also between the center sills and is substantially imperforatethroughout its area to form the bottom of the tender tank.

Suitable openin s are provided in the transoms, bolsters, an centersills to permit free passage of water therethrough.

Center sills 4 are of T shaped construction and are provided above thebottom web 16 and extend longitudinally the full length of theunderframe between the end sills. These center sills are spaced so thatthey are located directly below the vertical longitudinal supports 17for the coal hopper at the front end of the tender.

It is apparent that the improved type of construction permits the use ofa simpler and lighter casting than previous constructions having a boxshaped center sill extending the full length of the underframe andspaced longitudinal members on each side of the box shaped center sillat the front end for supporting the vertical longitudinal bracingmembers below the coal hopper.

Draft gear pocket 15, provided below the web 16 and the rear end sill 3,has spaced vertical webs 18 spaced a less distance apart than the spacedcenter sills 4 located above the web 16. Longitudinal reinforcingmembers 19 are provided above the web 16 as integral parts oftheunderframe'and in vertical alignment with the vertical webs 18.

Transom member 20 is of substantially box shaped construction and isprovided between the spaced center sills 4 and is integral with saidcenter sills and the reinforcing members 19 to transmit the pulling andbufiing forces to the center sills 4:.

Obviously various features and details herein disclosed may be modifiedwithout causing departure from the spirit of the in vention andexclusive use of all features coming within the scope of the claims iscontemplated.
